During one of your missions, you and the turtles had found a mutant egg.

Upon hatching, a small mutant turtle emerged, reminiscent of the rest of the team.

Leonardo grew concerned about the mutant's attachment to you, asking, "Where did this creature come from?"

Donnatello observed, "It appears to be a mutant turtle, but its origin is unknown."

Michelangelo grinned and teased, "It thinks you're its parent!"

Frustrated, Raphael interjected, "Shut up, bonehead. This could be serious."
